SASH FASTENER.

Application filed May 24,

sition and thus provide greater security against the opening of sash bythieves and burglars.

In the drawings of one embodiment of my invention described andillustrated herein,

Fig. 1 is a plan, partly broken out for convenienee, showing the bolt inunlocking position;

Fig. 2, a similar view with the bolt in locking position; I

Fig. 3, a similar view on a smaller scale showing the fastener on a sashand in unlocking position;

Fig. 5, a cross-section detail on the line 55, Fig. 1;

Fig. 6, a plan of the fastener in adjustable looking or ventilatingposition; and

Fig. 7, a. partial elevation of two window F sash, partly open andlocked withmy novel fastener.

' Referring first to Figs. 1, 2, my novel'tastoner comprises a baseplate 1 of suitable size and material, as metal, provided with apertures2, for receiving screws to secure the plate to the top of the lower sash22. Fig. 3.

The inner end of the plate, Figs. 1, 2, which overlaps the inner edge ofthe sash has an eye 3 while the opposite and outer end carries a housing4; fashioned to provide two.

curved tongues or fingers 5, 6, bent upwardly and inwardly from the edgeof the plate and constituting bolt and handle stops hereinafter reterredto, for the handle and bolt.

A bolt operating handle 7, Figs. 1 to. 4;, herein in the shape of anelongated bail or loop, has one end curved downwardly and laterally,engaging the eye 8, and its opposite end provided with a bolt, or, as inthis case, by being bent outwardly under the housing 1, to form the bolt8.

The plate 1 is provide centrally with two laterally extended, upstandingand spaced ribs 9, 10, which act as a detent and a withdrawn bolt stopsrespectively for the handle 7 at opposite sides thereof. The handle 7.Fig. 1, is provided at a point near the bend forming the bolt with aflattened or grooved 1927. Serial No. 193,792.

section 11 which enables the bolt end of the member 7 to be slidlongitudinally, Figs. 1, 2, beneath the fingers or stops 5, 6, inassembling.

The parts being assembled as in Figs. 1 to 4, the plate is secured tothetop of the lower sashnear the edge thereof with the handle lying downupon the sash and the free side of the handle member between stops 9,10, Fig. 1. A plurality of holes 12 are drilled in the front face of theside stile13 of the upper sash 1 1,

Fig. 3, sufficiently deep to receive the bolt 8 when in described andlocking position. Preferably a short piece of metal tubing large enoughto receive the bolt 8 is then driven into each hole 12 to prevent thehole from being.

enlarged bythe action of the bolt in entering and withdrawing from thehole,

WVhen the sash are both closed, Fig. 4, and it is desired to lock them,the handle 7 is raised upright until its resiliency frees it from. the

rib or Withdrawn bolt stop 10, then is lowered until it is substantiallyparallel with the top of the lower sash 22 when it spreads, owing to itsresiliency, and the bolt 8 slides outwardly beneath the fingers or stops5, 6, and into the aperture 12, when the handle is again raised toposition, Fig 2, and left to rest behind the ear 15 on handle stop (3. I

In this position it will be clear that the sash are both locked againstupward or downward movement, and no knife blade or the like slid upbetween the twosash could be used to throw the bolt 8 laterally tounlock it, nor could the bolt be worked backwardly and withdrawn fromthe aperture 12 because of the withdrawnbolt stop .5.

If it is desired to leave the fastener so that either sash or both canbe opened part way for ventilation only or in flCljUSll-ftblfi lockedposition, then after the bolt 8 has slid into the hole 12 the handle 7is not raised as described, but is left lying on top oi the lower sash,in adjustable locking and ventilating position, Fig. 6.

Now it either sash or both are moved part way, the movement of one sashrelative to the other will cause the bolt 8 to turn in its housing andagainst the corner of the slit 23 of the plate 1 as a fulcrum and thehandle 7 to equal to the length of the handle, see Fig. 7,'

- shown in Fig. 6.

Neither sash, however, can be moved a greater distance than the lengthof the handle permits, the handle being made of desired length with thisfeature in mind. This feature permits a sash to be raised or lowered alimited distance as desired at night, for instance, or at any time forventilation, with the assurance, however, that it cannot be moved anyfurther and thus the security of the lock in an adjusted position isalso obtained.

This lock is of great convenience on any sash, but particularly for useon sash in bungalows where the sleeping rooms are on the ground floorand where a partlyopened window leaves an especially favorableopportunity for annoyance.

This invention isn'ot limited tothe precise embodiment thereof describedand illustrated." r

Claims 1. A sash fastener comprising a fastener plate, an unlocking boltstop thereon, a bolt housing hai'ing a bolt' therein andahandle slot, ahandle for the bolt straddling the lower sash when in adjustable lockingposition, the handle constructed and arranged to swing to an uprightposition and permit the lower sash to be raised a limited distance.

2. A sash'fastener'comprising a base plate with an unlocking boltstopthereon, a bolt housing. a bolt therein, a bifurcated handle for thebolt, swingingly mounted in the housing, and constructed and arranged toreceive its sash when either sash ismoved relative to the other topermit limited movement thereof and locking engagement against,unlimited movement.

3. A sash fastener comprising a base to be secured to the upper edge ofthe lower sash, a bolt thereon, with a sash spanning handle and movablein a plane substantially parallel with the sash for operating the bolt.

4. A sashfastener comprising a base to be secured to the upper edge ofthe lower sash, a sliding bolt thereon having a sash spanning,vertically swinging and relatively sliding handle and mo'vable'in aplane sub- 5. A sash fastener comprising a base plate to be secured tothe upper edge of the lower sash, a bolt housing thereon, a withdrawnbolt stop on the plate, an extended bolt stop thereon, and a handle stopon the housing.

6. A sash fastener comprising a base plate to be secured to the upperedge of the lower sash, a handle pivoted thereto, a bolt housingthereon, a slidable bolt thereon, a detent and a withdrawn bolt stopthereon andan eX- tended bolt stop also on the plate.

7. A sash fastener handle with a bolt forming end thereon and a housingtherefor with a handle channel thereunder, and a groove on the handlesubstantially parallel with but in a different vertical plane from thebolt to permit adjustn'ient of the handle relative to the housing.

8. A sash fastener comprising a base plate to be secured to the upperedge of the lower sash, a withdrawn bolt stop thereon, a bolt housinghaving a passage thereunder for the movement of a handle, and an exendcdbolt stop, and a handle stop also on the housing.
